Abstract

Nipah fruit is a type of palm that grows in coastal areas. The benefits and efficacy of nipah fruit besides being consumed as processed food can also be used as an alternative source of traditional medicine. Tarakan City as a coastal area has high potential for mangrove forests. Likewise with the number of nipa palms. However, the nipa fruit industry has not yet flourished in society and is neglected. So far, nipah fruit is only eaten as it is, and only focuses on utilizing tree trunks and leaves. Seeing this phenomenon, the Team conducted training activities for making Nipah Fruit processing to become Bread Jam. In addition, the Team also identified business potential financially which could be a reference for Partners in developing products. The activities ran smoothly and the enthusiasm of the Partners was evident in the full involvement of the Partners, both in terms of training and mentoring. The results of the calculations from the financial aspect stated that the Nipah Fruit processed product business was profitable.     Abstrak: Buah nipah adalah sejenis palem yang tumbuh di kawasan pesisir. Manfaat dan khasiat Buah Nipah selain di konsumsi sebagai olahan makan manfaat buah nipah juga bisa di jadikan sumber alternative pengobatan tradisional. Kota Tarakan sebagai kawasan pesisir memiliki potensi hutan mangrove/bakau yang tinggi. Begitu pula dengan banyaknya pohon nipah. Namun demikian, industri buah nipah belum marak di masyarakat dan terabaikan. Selama ini buah nipah hanya dimakan begitu saja, dan hanya fokus memanfaatkan batang pohon dan daunnya saja. Melihat fenomena tersebut, Tim melakukan kegiatan pelatihan pembuatan pengolahan Buah Nipah  untuk menjadi Selai roti. Selain itu Tim juga melakukan identifikasi potensi usaha secara finansial yang dapat menjadi acuan bagi Mitra dalam mengembangkan produk. Kegiatan berjalan dengan lancar dan antusiasme Mitra tampak pada keterlibatan Mitra secara penuh, baik pada sisi pelatihan maupun pendampingan. Hasil dari perhitungan dari aspek finansial menyatakan bahwa usaha produk olahan Buah Nipah mendapatkan keuntungan.

Abstract

UMKM menjadi salah satu motor penggerak ekonomi di Indonesia. Namun demikian, UMKM masih berkutat pada lingkaran masalah dan kendalanya. Tidak hanya pada proses produksi melalui akses permodalan dan bahan baku, proses mengenalkan dan memasarkan produk menjadi permalahan tersendiri. UMKM Kembang Turi juga mengalami permasalahan serupa sejak mendirikan usahanya. Memasarkan produknya tidak hanya sampai produk terjual saja, bagaimana produk memiliki umur yang panjang di masyarakat menjadi tantangan bagi Kembang Turi. Kegiatan pelatihan dan pendampingan tentang bauran pemasaran menjadi solusi yang ditawarkan Tim Kegiatan. Melalui peningkatan pemahaman dan pengetahuan pada aspek pemasaran, dapat meningkatkan nilai jual produk. Hasil kegiatan menunjukkan bahwa Mitra memiliki peningkatan pemahaman pada konsep bauran pemasaran. Mitra juga mampu mengolah dan mengembangkan strategi pasar produknya. Mitra berharap kegiatan dapat berlangsung secara kontinyu.

Abstract

Pembangkit listrik tenaga gelombang laut sangat memungkinkan untuk dikembangkan di Indonesia. Selain memiliki potensi wilayah perairan yang sangat luas, penelitian terkait pembangkit listrik tenaga gelombang laut juga sudah banyak dilakukan dan terus dikembangkan hingga saat ini. Sebagai langkah awal sebelum melakukan penelitian lebih lanjut, dibuatlah wave tank skala laboratorium sebagai media untuk mengamati karakteristik gelombang. Tinggi dan panjang gelombang merupakan salah satu parameter yang dijadikan tolak ukur dalam penelitian ini. Desain pembuat ombak tipe piston dengan ukuran tangki yang sudah ditentukan, yaitu panjang 150 cm, lebar 35 cm, dan tinggi 35 cm dibuat sedemikian hingga dengan menghitung beban mekanik. Metode penelitian yang digunakan ialah perancangan teknik. Hasil rancang bangun menghasilkan mesin wave tank model piston dengan ukuran rangka, yaitu panjang 155 cm, lebar 40 cm, dan tinggi 122 cm yang digunakan untuk menopang tangki, motor listrik, dan wavemaker. Jenis penggerak yang digunakan yaitu model piston dengan satu kecepatan putaran yang diatur oleh dimmer. Tinggi gelombang yang dihasilkan bervariasi mulai dari 1,1 cm – 2,5 cm sedangkan panjang gelombang yang dihasilkan bervariasi juga yaitu, 10,5 cm – 20,5 cm.

Abstract

The application of coconut coir in polymer composites is often restricted by poor interfacial adhesion due to the fiber’s hydrophilic nature. This study investigates the enhancement of tensile strength in coconut coir–epoxy composites via microwave-induced liquid plasma treatment with an electrolyte medium. The experiment employed a randomized design with four fiber treatment groups: untreated (control), plasma-treated in distilled water, plasma-treated in 10% NaCl, and plasma-treated in 10% NaOH. The plasma process was conducted at 400 W for 5 minutes under vacuum conditions (60–70 cmHg). Tensile test results indicate that the electrolyte medium significantly influences the treatment effectiveness. Plasma treatment in a 10% NaOH medium achieved the highest average tensile strength (5.70 MPa), corresponding to a 9.2% improvement over untreated fibers. In contrast, plasma treatment in distilled water resulted in a 21.6% reduction in tensile strength (4.08 MPa). The observed enhancement in the alkaline medium is likely related to combined chemical and physical effects induced by the plasma environment, which may contribute to improved fiber–matrix mechanical interlocking. These findings demonstrate that selecting a conductive, alkaline electrolyte medium is critical for optimizing liquid plasma treatment of natural fibers for composite applications.

Abstract

Improving the thermal efficiency of biomass cookstoves remains essential for enhancing energy utilization and reducing fuel consumption in household applications. This study investigates the effect of geometric size reduction on the thermal performance of a galvanized steel biomass stove equipped with a 12 V DC blower. The original biomass stove constructed from galvanized steel plates with dimensions of 50 × 50 × 55 cm³ equipped with a 12 V DC blower was developed in 2022. Due to its relatively large size, the air–fuel mixture delivered to the combustion chamber was not fully optimized, resulting in a thermal efficiency of only 10%. To address this limitation, the stove dimensions were reduced to 40 × 40 × 40 cm³. The performance evaluation was conducted using the Water Boiling Test (WBT) method with two water volumes (2 L and 5 L) and three fuel masses (40%, 60%, and 80%). The results indicate that reducing the stove dimensions contributes to a significant improvement in thermal efficiency, reaching up to 14.6%.
